G-Code, CAD, and CAM discussions / Converting seconds to milliseconds
« on: October 21, 2008, 09:21:13 PM »
Hi,

My G-code contains dwell times in milliseconds, but Mach3 interprets it in seconds. So, I end up waiting 80 seconds burning my tool instead of a quick 80 milliseconds.
Anyone know how to ask Mach to interpret in seconds? I'm tired of editing my G-code.

Thanks
aleks.

General Mach Discussion / ellipical path in MACH3
« on: February 23, 2008, 09:55:15 PM »
Hi
Is there a way to have my CNC lathe cut an elliptical path? Or does G code only operate using circle arcs and lines?
Thanks
Aleks.

General Mach Discussion / Spontaneous Mach Turn Shut off
« on: January 23, 2008, 10:54:50 PM »
Hi, i used Mach turn for a whole project and things worked ok.
Now, i output a G-code file from mastercam X, ran it in Mach turn, and the thing shut off. I turned the computer on/off and it did it again.
Basically, after loading the file, Mach turn either shuts off right away, or moments later when i start setting up my job. What's going on?
Has anyone experimienced this?

General Mach Discussion / Mach3 ignores Feed Speed
« on: January 01, 2008, 06:55:32 PM »
Mach3 doesn't take into account my feeds. It just runs everything at rapid = 1000mm/min
What's the deal?

Thanks
Aleks.

Here's the G-code:

General Mach Discussion / Wrong Arc
« on: January 01, 2008, 04:39:55 PM »
When Mach3 decides which arc to choose between two point (X1,Z1) and (X2,Z2) with a given radius, it chooses the wrong one! see below
It takes the right direction, but it choose a different arc (any two points have two circles with the same radius going through them)
I'm not even sure how it's supposed to know which one to choose. Is it supposed to choose the shortest one?
Have can i fix this? Is it a Mach3 problem, or a Gcode problem.

Aleks.

G-Code, CAD, and CAM discussions / Mastercam Inverts my X axis
« on: December 31, 2007, 05:36:42 PM »
Hi, hoping someone can help me resolve my problem.
My G code files have inverted x axis values.
Even when i switch the machine definition control of the X axis turret to -Y or +Y, it doesn't make a difference in the output, i always get negative X values.
Even when i switch the construction plane into -D, Z. The problem persists.
I'm guessing i need to edit the post processor... anyone know how to do that?
Thanks
Aleks.

Hi,
I just got a Wabeco lathe, and i'm playing around with mastercam X Lathe.
Weird thing: backplotting seems to work properly... see new-1
but when i simulate the machining, it offsets the tool and destroys my part. new-2 shows the program after one pass.

Show"N"Tell ( What you have made with your CNC machine.) / iPod Nano Case
« on: December 30, 2007, 03:35:33 AM »
This was actually made on a manual mill... but i think it's cool enough to rival some of the things i've made on my CNC, which i got recently.

General Mach Discussion / Tool Slot Number too large.
« on: December 29, 2007, 09:48:01 PM »
Hi,
I just started making a tool library of all my tooling to be more organized. However, Mach stopped me because the Tool Slot Number (327) is too large... is there a way around this problem? 
Thanks
Aleks.
